Megger MIT320 Insulation Tester

Overview

The MIT320 is the second-highest specification model in Megger's MIT300 series, developed for today's electrical contractors. The digital/analog display with true analog arc response, 20 mm characters and backlight keeps readings clear on site, and a protective shock-absorbing case with rigid display cover stands up to everyday use.

Built-in safety features include a test lead interlock and lockout, live circuit voltage warning and a contact detection safety package that protects the instrument even if it is connected to a live circuit on the continuity range. The switched test probe and optional lead-null function speed up hands-free testing, and the tester accepts rechargeable batteries.

Features

  • Insulation testing at 250, 500 and 1000 V DC over a 10 kΩ to 999 MΩ measuring range
  • Insulation limit alarm adjustable from 0.01 MΩ to 999 MΩ
  • Continuity testing to 100 Ω with adjustable buzzer (1 to 20 Ω) and lead null to 9 Ω
  • Voltmeter function for AC/DC voltage measurement to 600 V
  • Resistance measurement from 10 Ω to 1 MΩ
  • Switched test probe for hands-free remote test activation
  • Digital/analog display with backlight and backlight selector ranges
  • IP54 weatherproof, rubber armored case; accepts rechargeable batteries
